In heavy rainy weather, with continuous rain, how can the photovoltaic power station inverter withstand it?

We survived the continuous "barbecue mode" with temperatures reaching 40 degrees for many consecutive days.

However, we are now in a continuous rainfall mode.

In the summer and autumn, there are frequent rainstorms, typhoons and cooling temperatures.

In the scene of rain disaster

Photovoltaic power stations are also vulnerable

How to maintain and service the inverter?

Next, let’s answer some questions about inverter protection on rainy days.

1. The photovoltaic inverter trips when it rains. What might be the cause?

1. In humid weather, the system leakage increases protection.

2. On rainy days, when there is not enough sunshine, the power is protected.

3. It is possible that the connection head is not tight.

If this happens, you must deal with it after the rain stops and the sun comes out. You can wrap the terminal heads with insulating tape and then observe whether the circuit breaker trips. If the circuit breaker continues to trip, you should report it to the maintenance center or local power management station.

2. How to ensure the stability of photovoltaic power stations on rainy days?

This starts with the early design of the project. When designing a power station, it is necessary to choose a suitable location. For example, if a photovoltaic power station is built on a roof, the roof fixed load, wind pressure load, snow pressure load, and earthquake load must be considered. Generally, the "Building Structure Load Code" will be followed, because only in this way can the power station be prevented from being damaged by rainy weather.

3. How to prevent summer lightning from causing serious damage to buildings and electrical equipment?

In the lightning protection design of independent photovoltaic power stations, good grounding is an important basis for the success of lightning protection measures. Reasonable design schemes should be selected and effective measures should be taken to do a good job in the lightning protection design of independent photovoltaic power stations. Direct lightning, induced lightning, and lightning waves should be prevented from damaging the equipment of independent photovoltaic power stations. Only in this way can the independent photovoltaic power stations be guaranteed to operate stably, safely, and reliably in the long term and provide users with high-quality electricity.

4. What should you do when you encounter a thunderstorm?

When thunder and rain occur, discharge will occur between the ground and the ground. If it comes into contact with relatively high buildings, outdoor communication facilities, etc. on the ground, it may cause electric shock and lightning strike. Note that on thunder and rainy days, the air switch under the meter should be turned off to prevent damage to electrical equipment. After the thunder and rain, close the switch.

5. What to do if the inverter is soaked in water?

First: Do not open the cover. Second: Use a multimeter to check if there is a short circuit at the external DC and AC connections. Third: Install the inverter into the system to test whether the device can generate electricity. Fourth: Contact the installer or inverter manufacturer for after-sales maintenance.
